TOILET' VENTILATOR.

Application'led April 25,1925. Serial No. 25,769.

sociation with the bowl and with the vent Iflxisting ventilators for this purpose have proven very satisfactory in actual service but have been lobjected to by the plumbing trade and by users because of the Vfact that they are comparatively difiicult of installation and because of the further fact that they are very conspicuous. The difficulty in installation arises when the piping for the plumbing fixtures does not properly align itself with the vent pipe so that the water closet bowl may be displaced a short distance either laterally or vertically from the desired position with reference to a vent pipe opening in the wall. Such fixtures as I am familiar with have not heretofore provided any means for readily compensating for slight inequalities such as those above referred to, and it is one of the -specific objects of this' invention to provide a Ventilating fitting which will have a more or less fiexible attachment with a receptacle connected with the vent pipe.

The conspicuousness of the Ventilating attachments with which I am familiar arises Vfrom the necessity forl avoiding the flushing pipe leading .from the tank to the bowl while maintaining a sufficient capacit for the efflux of gases from the bowl. This has heretofore been done by enlargin the chamber .of the passage `vertically an it laterally to pass on oneside of the flush pipe above referred to. The vertical enlargement makes the devices very conspicuous, and it is a further specific object lof this invention to provide adequate capacity without suggesting the purposes or functions of the device.

Another difficult in devices of this sort with which I am amiliar arises in the necessity'for making occasional repairs to the flushing pipe or its connections. It issometimes 'difficult to remove Ventilating attachments heretofore known in order to gain aecess to the flush pipe. The present device is so organized as to make its removal very simple' at suchtimes as the removal or repair "of theflush vpipe is necessary. In the drawings:vv

lFi ure 1 is a plan view'of a deviceem-l bodymg this invention.

offsetting Figure 2 is a side elevation thereof.

Figure 3 is a section taken on line 3 3 of Fi ure 2. `igure 4 illustrates a modified form of the invention adapted for use when the vent pipe is not to be installed in the wall. but must be disposed outside of the finish plaster of the partition.

Like parts are identified by the same reference characters throughout the several vlews.

The bowl is shown at 5, the seat 6, for the sake of clearness, being shown merely in broken lines. At 7 I have illustrated the usual'bolts by means of which the hinges for the seat 6 are secured to the porcelain body of the bowl.` The device which embodies the present invention comprises a Y-shaped tube, all parts of which are substantially rectangular in cross section. The broad centra-l portion 8 of this tube extends between hinge bolts 7 and the edge of the bowl where 1t opens beneath the seat 6. Atv

tire fitting comprising main pipe 8 and branches 1() and 11 is connected with the bowl simply through the medium of a transversely slotted platev l5 connected to the fitting and adapted to receive the hinge bolts 7 .through its slots. Obviously, when the hinges are superposed and threadedI onto bolts 7 and are tightened against the bowl, the. fitting will not only be confined against movement but, due to its symmetrical shape and fiat upper surfaceand due to the fact that all securing means are invisible, the

device will be very inconspicuous and in most instances wholly unnoticeable.

(2o-operating with the Ventilating fitting above described is a receptacle designated 105 inits entirety b reference character 17 and adapted to be p aced in the partition or wall immediately at the rear of the bowl and beneath the tank. This receptacle comprises a box A18 providing an interior chamber 19 which communicates with the vent pipe 20 through an aperture 21 defined by a sleeve 22 which is preferably iformed integrally with box 18 and receives the lower end of the vent pipe.

The front of the box preferably comprises a plate 25 which may conveniently be formed integrally therewith and projects therebeyond on at least two of its margins. This plate is intended to overlie thelath 26, of the partition and to be secured thereto. Its front face will be flush' with the plaster 27 when so secured. Any Vother suitable supportin strips may be used at 26 in place of lath i greater strength is desired, but thereceptacle is subject to no particular loa In the face plate 25 are a pair of laterally spaced openings 29 and 30 adapted to receive the ends of the branch pipes 10 and 11. Openings 29 and 30 are preferably slightly smaller than the iinterior chamber 19 in order to afford clearance orl relief for relativemovement of the arms with respect to thereceptacle.

There is nothingr which secures the arms within the receptacle lexcept the juxta-position of the bowl and partition and the fact that the Ventilating fittin is secured to the bowl by the hinge bolts t ereon. The arms 10`r and 11 are freely adapted for telescopic movement into and out of the receptacle, whereby a given length of arm on the ventilating fitting will be serviceable for a great many different installationsvregardless of the specific distance between the bowl and the partition. Furthermore, the clearance surrounding the open'in s 29 and 30 is such as to permit a considera le degree of lateral and vertical oscillation of the Ventilating fitting with reference to the receptacle 17. As a result, it will be clear that even if the ipe does not conform accurately to the plans, this device may nevertheless be installed witbout de rting from its standard construction. he connectionl between the ventilatin 'fitting and the receptacle Vmay be very tight fitting andat the same time, cons' ering the comparatively great volume capaciy of the fitting, there will be a very t exibility between it and the receptac e.

.Where the installation is made' in an old house, in which the partition is already-plasteredup and it will bc diicult to installthe' vent plipe 20 in such partition, it becomes desira le @to modify t e device above described in such a manner that while reserving many of the advantageous features above rewerred to the device will nevertheless be adapted to communicate with a receptacle placed outside of the artition wall. To this end I have design the Fi re 4 construction, in which the Ventilating fitting, including main pipe 8 and branch pipes 10 and 11, is constructed exactly along the lines above indicated with the exception that it may be nry to cut of the arms 10 and 11 in order to reduce their length. The principal difference between the two devices arises in the 'receptacle which, in the Figure 4 construction, must'be so devised that it can be located beneath the flush tank and outside of the partition.

In this modified construction the design of-the receptacle should be such that it will not interfere with the flush pipe 12, and accordingly, the receptacle is provided with diverging arms 32 and 33 which unite at 34 upon one side of the iiush pipe and lead to a laterally ofset port 35 which may communicate with the vent ipe 20. It will be understood that when t e vent pipe is not in the partition it mustl be laterally oiset in order to clear the tank, and this will account for the location of the opening -35 in the receptacle.

Arms'lO and 11 are telescopically receivable in this receptacle just as they were in that previously described, and in fact the construction of the ventilating fitting is standard in both installations. The Figure 4 construction, like that shown in the previous views, provides a comparatively high degree of flexibility between the fitting and receptacle while being as incnspicuous as is 'possible in a device in which vthe vent i pipe is outside'of the artition.

It will be apparent om the foregoing description that the objects of the vinvention are fully satised, and that a novel` and simple device has been disclosed for the purposes aforesaid.

I claim: A

1. In a device of the character described, the combination with a receptacle having an interior-chamber, a-.vent opening and a pair of spaced apertures; of a Ventilating fittin comprising a main conduit and a pair o substantially parallel branch conduit p0r' ids tions complementary to said apertures and telescopically receivable therein, said receptacle being provided with means for securing it to avpartition, and said. mainconduit portion bein rovided mith apertured lugs adapted to engaged by the hinge fitting of a water closet bowl@ 2; In a device of the character described, the combination with a receptacle comprising a horizontally elongatedmchamber having spaced apertures in its front and having an opening in its top, of a flange .on said receptacle at 'its front 'and'adapted to comi prise a face plate for the mounting of. saidq receptacle, and an annular collar formed about saidl opening. on said receptaclel and adapted to receive connectionwith 'a vent pipe, together vwith a' Ventilating fitting. comprising spaced conduit portions telesco ically receivable into the apertures of said receptacle. 1 v
